If your 360 footage has been taken in low light conditions, you can use the brightness and contract filters to improve visibility.
Step 1
Click on the sun button in the top left of your 360 scene.
Step 2
Adjust the brightness and contrast sliders. As a general rule for dark scenes, increase brightness and reduce contrast for best results.
Note: these settings will persist as you navigate to other 360 scenes, until you next leave the 360 viewer. Hit Reset to return to default settings.
Simple as that!
